N.E.R.D return with Rihanna duet Lemon

N.E.R.D have dropped their first new song in seven years, 'Lemon', featuring Rihanna

N.E.R.D have dropped a collaboration with Rihanna called 'Lemon'.

The hip-hop trio - featuring Pharrell Williams, Chad Hugo and Shae Haley - have been teasing fans all week about their comeback and, on Wednesday (01.11.17), they released their first track since 2010's 'Nothing' LP, featuring a rap from the Bajan beauty.

The 'Wild Thoughts' hitmaker spits: "I get it how I live it / I live it how I get it. I pull up with a lemon ... your eyes get acidic."

Rihanna, 29, has only released chart-topper 'Wild Thoughts' with DJ Khalid this year.

The 'She Wants to Move' hitmakers kicked off speculation about their return by putting up a number of posters at Tyler, The Creator's Flog Gnaw festival over the weekend.

They featured an acronym for the trio's name, which read: "No_one Ever Really Dies."

The same message also appeared on their official website and all of their social media profiles.

Pharrell - who has been busy with his solo career whilst the trio were inactive - confirmed in 2015 that they will definitely be doing another record.

When asked in a Twitter Q&A by a fan: "Are you going to make another N.E.R.D. album?", the 'Happy' singer replied: "OF COURSE!".

Despite not having recorded new music together since the release of their fourth studio album, Pharrell and Shae both appeared on stage together at Camden's Roundhouse in London in September 2014, and teased new material from the band.

Joining the 'Freedom' hitmaker on stage, Shae said: "It feels good to be back in London. When we released our first album back in 2001 and first crossed the Atlantic, this was the first place to embrace us. You're going to like this s**t we're going to release."
